FLEHS-IV

Flemish Environment and Health Study, cycle 4 | Teenagers

Description

FLEHS IV is the fourth cycle of the Flemish Environment and Health Study conducted in Flanders with sampling between September 2017 and June 2018. The objective of FLEHS IV was to investigate the relation between environmental pollution and human health by measuring exposure and effect biomarkers and specific health outcomes in teenagers. The specific aims were to i) establish reference values and time trends of internal exposure to toxic chemicals and for comparison to international studies and health-based guidance values, ii) investigate associations of biomarkers and health outcomes with residential surroundings, iii) investigate whether eco-behavior is associated with exposure and health, iv) identify and characterize exposure to emerging chemicals. Participants of FLEHS IV were recruited via schools. A stratified clustered multi-stage sampling strategy was applied to enroll equal numbers of participants across both sexes and to represent all educational levels and Flemish provinces, proportionally to the general Flemish population. The following exclusion criteria were applied: data of more than one questionnaire missing, blood and urine sample missing, being held back in school for more than one year and attending a boarding school. A participation rate of 34% was achieved. As an incentive participants received feedback on their personal results and 20 euro. The study recruited a total of 428 teenagers between 14-15 years of age. For FLEHS IV a subset of 300 individuals was included in the HBM4EU aligned studies sample. Metadata information of the study can be found in IPCHEM.
